The management of greenhouse vines needs to do the following:
1, timely buckle shed: According to the characteristics of grape growth and climate characteristics, generally in late December, after the grape has spent dormancy period after the shed. The plastic film should be made of light-transmitting, non-drip film, which should be covered at night to facilitate heat preservation.
2. Control the temperature and humidity in the shed: grapes can be unearthed and put on shelves after the shed. After the grapes were unearthed, they were poured with enough water. During the first week of actual and low temperature management, weeds were kept down during the day to maintain high humidity. During the day, the temperature was maintained between 20-25°C and the night temperature was approximately 0-5°C. The humidity is kept above 95%. The grape enters the budding stage, and the greenhouse temperature should be strictly controlled during the day to prevent the shoots from “blinking†and the emergence of irregular shoots; the suitable temperature is 22-28°C and the humidity is about 85%. During the growing season, the temperature should be controlled at 22-28°C during the daytime and 12°C at night to prevent overheating, resulting in new shoots, flower spikes, and poor flower differentiation. Afterwards, the drafts were drafted at 9:00 a.m. and then put down at 4 pm. . Pay attention to the wind, the relative temperature of the flowering period is about 50%, and the other growing period is between 55% and 60%.
3, water and fertilizer management: combined with back-filled cold soil after unearthed grapes, per acre high quality organic fertilizer 4-5 side, about 75 kg compound fertilizer. Afterwards, we will focus on applying special fertilizers such as promoting strips, expanding fruit, and coloring, as well as spraying nitrogen, phosphorus, potassium, and trace elements. Nitrogen fertilizer is the main fertilizer before flowering, and compound fertilizer is the main flowering and young fruit stage. From the hard-core stage to the fruit-picking stage, phosphorus and potash fertilizers, especially potash fertilizers, are mainly used. In order to increase production, special attention should be paid to the supplementation and spraying of boron. Watering is generally combined with fertilization, according to soil moisture, small water, pouring, thin fertilizer and ground facilities, must not flood irrigation.
4. Pest control: (1) Thoroughly clean up before the shed: The sheds are generally lighter. The key to disease prevention is disinfection during the dormancy period. After the deciduous grape is combined with the winter cutting, the diseased branches and vines must be completely cut off, the old bark that may be borne by the scraping branch may be scraped off, and the diseased bodies such as fallen branches, defeated leaves, tendrils and rotten fruits may be removed. And burned together. (2) Timely prevention after the shed: After the grapes are unearthed, they will reach the pompon period. To spray the whole plant once 3-5 Baume degree lime sulfur mixture and 0.5% pentachlorophenol nano-mixture, the ground and the rod can be directly sterilized with 1% pentachlorophenol nano-spray. This has a great effect on reducing the incidence of early infection. (3) Reasonable prevention and control during growth period: During the growing period, greenhouse vines should pay attention to the occurrence of old age sickness due to the relatively high air humidity. Before and after flowering, spray one or two times 200 times. Fruit coloring period attention to prevention of white rot, anthrax. Can be used Fujimi pairs, 500 grams of sulfur powder and calcium carbonate 12 kilograms of mixed powder for ground application, the amount of 2 kg per acre. Can also spray 75% of chlorothalonil 400-600 times, 50% of carbendazim, 70% of thiophanate-methyl 600-800 times for control.
